To go back: I feel like a twit! I did not read the whole instructions to the end. So I save the zipped backup ON MY COMPUTER ....
Then when the nameservers have already changed to direct from my old doc-computer.com to new host, I have installed a fresh copy default of
WP, installed WPClone plugin.
Then I see that it has to be restored from a URI [is that the same as a URL?]. That is when I tried the URL from Dropbox and from my computer and neither worked. AAAAARRRRRRRRGGGGGGGGHHHHHHHHHHH!
Doc-computer.com and a whole lot more!
Any suggestions VERY welcome. I know computers but am still learning WordPress. Have not looked into the way it works. So phpAdmin confuses me.
